title: Effect of combined gonadotropin-thyrotropin treatment on development of testis and ovarium in the chickling.
abstract: Both TSH and gonadotropins stimulate the gonads in the perinatal period. Gonadotropins influence primarily the parenchyma and they induce an increase in the diameter of seminiferous tubules, and of the thickness of the ovarian cortex. TSH acts primarily on the interstice, but it acts also on the parenchyma and this action is more pronounced in the testis than in the ovary. The hormones can replace each other, and gonadotropins enhance the effect of TSH on the interstice.
